| Abstract: | The anti-active jamming performance of centralized coherent MIMO radar is studied. The MIMO radar signal interception range, the effect of received signal sorting capability of jammer and the anti-active sidelobe jamming capability is considered. Based on the radar interception function, the interception range of MIMO radar and the mainlobe and sidelobe of phased array radar is compared. The space-time pseudorandom characteristics of synthesized signal which is combed by MIMO radar transmitted multiple orthogonal signals is discussed. The capability of suppression different type sidelobe jamming of different array structures of MIMO radar is analyzed。Theoretical formula derivation and simulation result is given to prove the analysis. |
